Perhaps a real indication of grade can't occur until they mine bulk samples.
One of the changes that can made is to mine minimum mining width and use sludge hole drilling to test for near-development ore. According to my chat with someone in the industry, this will reduce any unnecessary dilution of ore.
Another possible way to estimate grade is to focus on comparing truck sampling to face channel sampling.
Just my thoughts based on discussions. I can't recommend a buy or sell to punters, but I do suggest lengthy discussion with the company before doing anything regrettable.
